A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
What is coeffitient of stactic n kinetic friction?
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
When the block of mass is increased is there an increase in the value of coefficient of kinetic friction?
No, coefficient of friction is dependent on the materials in contact, not their mass. However the FORCE of friction will increase as the mass increases in this case.
What is the definition of kinetic?
Friction generated between two dry surfaces in contact during motion. Kinetic frictionis a product of the coefficient of kinetic friction and the normal reaction force. It assumes a constant value regardless of the amount of applied force or the speed of the motion. Its value is always less than the limiting friction between the same two surfaces.
Is coefficient of friction or coefficient of limiting friction are same?
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.
What is the coefficient of kinetic friction between aluminun and felt?

What is the formula for the coefficient of kinetic friction?

How does the roughness of surfaces that are toughing affect the friction between the surfaces?
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic

Give an example of friction?
Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
What is the coefficient of kinetic energy?
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
What are the two kinds of friction?
There are two types of friction : static friction and kinetic friction. Static friction occurs when two objects are touching but are not moving relative to each other. For example, static friction can prevent a box from sliding down a slope. The static friction between this box and the slope (and between any objects) can be calculated using the equation : Fs = µsN where µs is the coefficient of static friction and N is the normal force. Kinetic friction occurs when two objects are touching and moving relative to each other. For example, the kinetic friction slows down a box sliding down a slope. Also, when two surfaces rub together, there is kinetic friction. The kinetic friction can be calculated using the equation: Fk= µkN where µk is the coefficient of kinetic friction and N is the normal force.
